IGMP Snooping Status — Indicates if IGMP snooping is enabled on the VLAN. The
possible field values are:
— Enable — Enables IGMP Snooping on the VLAN.
— Disable — Disables IGMP Snooping on the VLAN.
•
Auto Learn — Indicates if Auto Learn is enabled on the VLAN. If Auto Learn is
enabled, the device automatically learns about the existing multicast routers. The
possible field values are:
— Enable — Enables auto learn.
— Disable — Disables auto learn.
•
Host Timeout — Indicates the amount of time the host waits to receive a message
before timing out. If an IGMP report for a multicast group wasn’t received on the port
from any host (located on the port), the port is deleted from the membership list of
that group. The default time is 260 seconds.
•
MRouter Timeout — Indicates the amount of the time the Multicast router waits to
receive a message before it times out. If any MRouter message (IGMP query or any
other multicast router message), wasn’t received on the port, the port is deleted from
the MRouter membership port list. The default value is 300 seconds.
•
Leave Timeout — Indicates the amount of time the host waits, after requesting to
leave the IGMP group and not receiving a Join message from another station, before
timing out. If a Leave Timeout occurs, the switch notifies the Multicast device to stop
sending traffic. The Leave Timeout value is either user-defined, or an immediate leave
value. The default timeout is 10 seconds.
